Reese Witherspoon took her son Tennessee to the Happiest Place on Earth on Monday — and it looks like this mother-son duo is certainly ready for Halloween!

While posing alongside Minnie Mouse during Disneyland's Halloween Time celebration, the 40-year-old threw on an adorably-themed hat while the four-year-old cutie rocked Spider-Man face paint (above). So cute!

The official trailer for Big Little Lies just dropped, and HBO's limited series is pulling some of the biggest actors and filmmakers from the big screen away for a television even that looks compelling, chilling, and REALLY well shot!
